Hayden Smelter is a copper smelter at Hayden, Arizona, owned and operated by ASARCO. It has a 305 meters (1,001 feet) tall chimney, which is the tallest free-standing structure of Arizona. It processes copper from the Ray mine.
In 2011, the Environmental Protection Agency took action against the smelter for releasing "illegal amounts of lead, arsenic and eight other dangerous compounds."[2]
